I’m interested in buying a pedometer for walking (under $40). I don’t really need anything fancy, just one that will tell me how far I’ve gone distance wise and how many steps I’ve taken. However I have two dogs that I like to walk with. To minimize pulling one uses a chin leader/head collar, and the other a harness. What I need to know is if I can use a pedometer while walking the dogs or if their movement and occasional pulling will interfere with it. Also if you believe I can, can you suggest one that you believe would work well. Thanks
